Bài 11: Tìm x trong các tỉ lệ thức sau:

1) \(\frac{4}{x} = \frac{8}{x+1}\)
2) \(\frac{6}{x-3} = \frac{7}{x-5}\)
3) \(\frac{|4-x|}{3} = \frac{x-2}{5}\)
4) \(\frac{x-1}{x+5} = \frac{6}{7}\)
5) \(\frac{x-3}{x+5} = \frac{5}{7}\)
6) \(\frac{x}{x+16} = \frac{7}{35}\)
7) \(\frac{x-3}{5} = \frac{5-2x}{11}\)
8) \(\frac{7x+1}{4} = \frac{2x-9}{3}\)
